Purchasing the Item

Now that the item is in the Product Advertising API remote shopping cart, the customer can purchase it. You can implement this task using a user interface button labeled, for example, Proceed to Checkout. The actual process of getting the customer's billing and shipping information, and method of payment is handled entirely by Amazon in what is called the Order Pipeline. The only task your application or website must implement is sending a PurchaseURL in a request to Amazon. Every cart operation returns the PurchaseURL. It contains all of the information necessary for Amazon to locate the customer's Product Advertising API remote shopping cart on its servers. The PurchaseURL also contains Associate information so that if an Associate brokered the sale, they receive a commission.
